What are the disadvantages of titanium?
What are the disadvantages of titanium? Well, the main disadvantages include high cost, low elastic modulus and an unstable creep. Casting titanium is a difficult process as it includes more cost and workforce. Low elastic modules means lower stress to strain ratio.
Why are some titanium rings so cheap?
One reason is that they are so inexpensive is that the metal is not worth very much. Titanium bands are less expensive than those crafted from platinum, white gold or tungsten. The price of gold is at present around $900 per ounce, while the platinum can reach an astounding high of $2,000 per ounce.
